Apple Pay Merchant ID CSR error



Need some help in setting up the certificates. I am using the integration guide provided here at to set up apple on web for our app.


Here’s where I did :

  1. Grabbed the CSR from Moneris, got it signed in apple for the “Apple Pay Processing Certificate” and uploaded it back in Moneris’s MRC. This worked and you can see our id “” (store-id – 1)
  2. Then in the client certificate area, after downloading the CSR and uploading the in Apple for the “Apple Pay Merchant Identity Certificate”, I get an apple error for “Invalid CSR”. So seems like the CSR being generated from Moneris could be invalid.

Could you please investigate this issue and let us know what could be going wrong ?
